Re: C++ struct in yyparse()?

hello,

i'm sorry if this is a bit off topic but perhaps some of you here have
experience
with c++ with lex/yacc and can help me.

i wrote a small lexer/parser using lex/yacc. i'm using c++ as the
language to interface with lex/yacc generated code. i have the
following user defined
struct for YYSTYPE to populate the data that is parsed.

/*!
 * This union is used by the yyparse() routine to hold the
information
 * that is accumulated during the parsing of a technology library
file.
 * As tokens are collected, and rules from the grammar are
 * deduced, the data can be stored by creating one of the appropriate
 * structures and populating it with values.
 */
typedef union MY_YYSTYPE
{
  TechLib::Element *element; /*!< An element is a gate or a
latch. */
  TechLib::Gate *gate; /*!< A logic gate. */
  TechLib::Expression *expr; /*!< The logic expression of an
element. */
  TechLib::Function *function; /*!< Logic function of an
element. */
  TechLib::Pin *pin; /*!< Pin information about a
pin. */
  list<TechLib::Pin *> *pinlist; /*!< A list of pins. */
  TechLib::Latch *latch; /*!< A latch. */
  TechLib::Constraint *cst; /*!< Constraints on the latch. */
  list<TechLib::Constraint *> *cstlist; /*!< List of constraints.
*/
  TechLib::Clock *clk; /*!< The latch's clock. */
  string *str; /*!< An identifier. */
  double val; /*!< A float value. */
  TechLib::Pin::PhaseT phase; /*!< Phase of an input. */
  TechLib::Latch::TypeT atchtype; /*!< Type of latch. */

};

as you can see its a bunch of pointers. in my yacc grammar i have to
do a bunch of new/delete statements to create the objects once rules
are
deduced. i would like to avoid this if possible. that is, i want to
make
YYSTYPE hold objects (and not pointers to objects).
one person briefly mentioned that i should put all
the above as objects (and not as pointers) inside a struct and then
have an anonymous union inside this struct as well which contains
pointers. i didn't understand him very clearly so i am not sure how
to
go about implementing the struct definition for YYSType. i'd
like to avoid using new/delete as much as possible to make it easier
on myself when debugging. i would appreciate if anyone can help me.
thanks for your time.
